I sympathize. My son speaks in three volumes: loud, shouting, and communicating with the deaf. The higher volumes seem to be associated with excitement and fatigue. We deal with this by increasing physical activity during the day and by providing a range of hyper stimulating discussion topics, so that any one glitch in the mental Matrix can be stemmed by dangling another appealing carrot. I hope he never ages out of this strategy, because I don't know that I have other ideas.

What is to give light must endure burning.
